BACKGROUND

The enzyme cyclic GMP-AMP Synthase (cGAS) catalyzes the synthesis of cyclic GMP-AMP (cGAMP) from ATP and GTP in the presence of DNA. This cGAMP then functions as a second messenger that binds to and activates STimulator of INterferon Genes (STING). The activation of IRF3 and the NF-κB signaling by this pathway results in the production of cytokines and type I interferons, which triggers an innate immune response to bacterial or viral infection. Genetic mutations that alter the balance of this pathway may result in an increased activation of the STING pathway, resulting in autoimmune and inflammatory diseases. For example, a loss of function mutation of TREX1 exonuclease, which digests DNA, can result in an accumulation of self-DNA in the cytosol, leading to excessive levels of cGAMP produced by cGAS and elevated expression of interferon induced genes in this pathway. Mutations in TREX1 are associated with systemic inflammatory diseases such as Aicardi-Goutieres Syndrome, familial chilblain lupus and systemic lupus erythematosus. Trex^(−/−) mice were shown to exhibit autoimmune and inflammatory phenotypes which are eliminated with genetic deletion of cGas in these mice (Gao et al., PNAS 112(42):E5699-705, 2015; Gray et al., The Journal of Immunology 195:1939-1943, 2015). Thus there is a need for inhibitors of the cGAS/STING pathway for the treatment of a variety of diseases.

DETAILED DESCRIPTION

STING (STimulator of INterferon Genes) is a central mediator for a cytosolic pathway that triggers type I interferon, in response to sensing cytosolic double-stranded (ds) DNA from infectious pathogens or aberrant host cells (Danger Associated Molecular Patterns, DAMPS) (Barber, Immunol. Rev 243: 99-108, 2011). Alternatively known as TMEM173, MITA, ERIS, and MPYS, STING was discovered using cDNA expression cloning methods as a MyD88-independent host cell defense factor expressed in macrophages, dendritic cells (DCs) and fibroblasts was found to induce expression of IFN-β and NF-κB dependent pro-inflammatory cytokines in response to sensing cytoplasmic DNA, in response to infection with herpes simplex virus (Ishikawa and Barber, Nature 455: 674-79, 2008).

While STING was discovered as being the critical sensor for inducing the production of IFN-β in response to infection with herpes simplex virus, the mechanism for this sensing function initially remained elusive. This conundrum was solved with the discovery of cyclic GMP-AMP synthase (cGAS), a host cell nucleotidyl transferase that directly binds dsDNA, and in response synthesizes a second messenger, c[G(2′,5′)pA(3′,5′)p] (cyclic GMP-AMP or 2′3′-cGAMP), which activates the STING pathway and induces IFN-β expression (Sun et al., Science 339: 786-91, 2013; Wu et al., Science 339: 826-30, 2013). This 2′3′-cGAMP product differed from bacterial-derived canonical cyclic dinucleotides, which were shown to respond differently to single nucleotide polymorphisms in the hSTING gene (Diner et al., Cell Reports 3:1355-1361, 2013; Gao et al., Cell 154:748-762, 2013; Conlon et. al., J Immunol 190:5216-5225, 2013). It was demonstrated that, while the bacterial-derived cyclic dinucleotides contained bis-3′-5′ linkages, cGAS produces a non-canonical, i.e., mixed linkage, CDN represented as c[G(2′,5′)pA(3′,5′)p] (Diner et al., Cell Reports 3:1355-1361, 2013; Gao et al., Cell 153:1094-1107, 2013; Ablasser et al., Nature 498: 380-84, 2013; Kranzusch et al., Cell Reports 3: 1362-68, 2013; Zhang et al., Mol. Cell. 51: 226-35, 2013). Cells without a functional cGAS are unable to express IFN-β in response to stimulation with cytosolic DNA.

Given the role of cGAS in the STING pathway and the role of type I interferons in various diseases, treatment with a cGAS/STING pathway inhibitor may have therapeutic benefit in a number of inflammatory, autoimmune, and neurodegenerative diseases, including, but are not limited to, systemic inflammatory response syndrome (SIRS), sepsis, septic shock, atherosclerosis, celiac disease, dermatomyositis, scleroderma, interstitial cystitis, transplant rejection (e.g. graft-versus-host disease), Aicardi-Goutieres Syndrome, Hutchison Guilford progeria syndrome, Singleton-Merten Syndrome, proteasome-associated autoinflammatory syndrome, SAVI (STING-associated vasculopathy with onset in infancy), CANDLE (Chronic Atypical Neutrophilic Dermatosis with Lipodystrophy and Elevated Temperature) syndrome, chilblain lupus erythematosus, systemic lupus erythematosus, rheumatoid arthritis, juvenile rheumatoid arthritis, Wegener's disease, inflammatory bowel disease (e.g. ulcerative colitis, Crohn's disease), idiopathic thrombocytopenic purpura, thrombotic thrombocytopenic purpura, autoimmune thrombocytopenia, multiple sclerosis, psoriasis, IgA nephropathy, IgM polyneuropathies, glomerulonephritis, autoimmune myocarditis, myasthenia gravis, vasculitis, Type 1 diabetes, Type 2 diabetes, Sjorgen's syndrome, X-linked reticulate pigmentary disorder, polymyositis, spondyloenchondrodysplasia, age-related macular degeneration, Alzheimer's disease and Parkinson's disease.

As used herein, “alkyl”, “C₁, C₂, C₃, C₄, C₅ or C₆ alkyl” or “C₁₋₆ alkyl” is intended to include C₁, C₂, C₃, C₄, C₅ or C₆ straight chain (linear) saturated aliphatic hydrocarbon groups and C₃, C₄, C₅ or C₆ branched saturated aliphatic hydrocarbon groups. For example, C₁-C₆ alkyl is intended to include C₁, C₂, C₃, C₄, C₅ and C₆ alkyl groups. Examples of alkyl include, moieties having from one to six carbon atoms, such as, but not limited to, methyl, ethyl, n-propyl, i-propyl, n-butyl, s-butyl, t-butyl, n-pentyl, s-pentyl or n-hexyl. The term Cm n means the alkyl group has “m” to “n” carbon atoms. The term “alkylene” refers to an alkyl group having a substituent, i.e. as used here in it is a bivalent alkyl moiety. For example C₀₋₃alkylene, as used herein as part of a substituent of another group includes a direct bond, a linear group —CH₂—, —CH₂CH₂—, or —CH₂CH₂CH₂—, or a branched group —CH(CH₃)—, —CH₂CH(CH₃)—, or —CH(CH₃)CH₂—, where C₂ or C₃ alkylene is preferably linear. For groups described as having more than one alkyl component, for example —N(C₁₋₃alkyl)₂, —C(═O)N(C₁₋₃alkyl)₂, —P(═O)(C₁₋₃alkyl)₂, or the like, the alkyl components may be the same or different. For example dialkylamino represents as —N(C₁₋₃alkyl)₂ includes N,N-dimethylamino, N,N-diethylamino, N-isopropyl-N-methyl-amino, and the like.

As used herein, the term “cycloalkyl” refers to a saturated or unsaturated nonaromatic hydrocarbon mono- or multi-ring (e.g., fused, bridged, or spiro rings) system having 3 to 30 carbon atoms (e.g., C₃₋₁₀). For example, a C₃₋₈ cycloalkyl is intended to include a monocyclic, bicyclic or tricyclic ring having 3, 4, 5, 6, 7, or 8 carbon atoms.

A bridged ring occurs when one or more carbon atoms link two non-adjacent carbon atoms. In one embodiment, bridge rings are one or two carbon atoms. It is noted that a bridge always converts a monocyclic ring into a tricyclic ring. When a ring is bridged, the substituents recited for the ring may also be present on the bridge. Fused (e.g., naphthyl, tetrahydronaphthyl) and spiro rings are also included. In the case of multicyclic rings, none of the rings is aromatic.

As used herein, “alkylene linker” is intended to include C₁, C₂, C₃, C₄, C₅ or C₆ straight chain (linear) saturated divalent aliphatic hydrocarbon groups and C₂, C₃, C₄, C₅ or C₆ branched saturated aliphatic hydrocarbon groups. For example, C₁₋₃ alkylene linker as used in describing Q¹ and Q² of Formula I herein is a C₁₋₃ alkylene intended to include C₁, C₂, and C₃ alkyl linker groups. These linker groups bind to the core Formula I and to T¹ or T². Examples of alkylene linker include, moieties having from one to six carbon atoms, such as, but not limited to, methyl, ethyl, n-propyl, i-propyl, n-butyl, s-butyl, i-butyl, n-pentyl, s-pentyl, or n-hexyl.

For example, the term “alkenyl” includes straight chain alkenyl groups (e.g., ethenyl, propenyl, butenyl, pentenyl, hexenyl, heptenyl, octenyl, nonenyl, decenyl), and branched alkenyl groups. In certain embodiments, a straight chain or branched alkenyl group has six or fewer carbon atoms in its backbone (e.g., C₂-C₆ for straight chain, C₃-C₆ for branched chain). The term “C₂₋₆” or “C₂-C₆” includes alkenyl groups containing two to six carbon atoms. The term “C₃₋₆” or “C₃-C₆” includes alkenyl groups containing three to six carbon atoms.

For example, substituted heterocycloalkyl includes those substituted with one or more alkyl groups, such as 2,2,6,6-tetramethyl-piperidinyl and 2,2,6,6-tetramethyl-1,2,3,6-tetrahydropyridinyl.

“Aryl” includes groups with aromaticity, including “conjugated,” or multicyclic systems with at least one aromatic ring and lacking a heteroatom in the ring structure. For example, a C₆₋₁₀aryl is intended to include a monocyclic, bicyclic or tricyclic ring having 6, 7, 8, 9, or 10 carbon atoms. Examples include phenyl, 1,2,3,4-tetrahydronaphthalenyl, naphthalene, etc.

“Heteroaryl” groups are aryl groups, as defined above, except having from one to four heteroatoms in the ring structure, and may also be referred to as “aryl heterocycles” or “heteroaromatics.” For example, a 5 to 10-membered heteroaryl ring is intended to include a stable 5-, 6-, 7-, 8-, or 9-membered monocyclic or 5-, 6-, 7-, 8-, 9-, or 10-membered bicyclic aromatic heterocyclic ring which consists of carbon atoms and one or more heteroatoms, e.g., 1 or 1-2 or 1-3 or 1-4 or 1-5 or 1-6 heteroatoms, or e.g. 1, 2, 3, 4, 5, or 6 heteroatoms, independently selected from the group consisting of nitrogen, oxygen, sulfur, selenium, and boron. The nitrogen atom may be substituted or unsubstituted (i.e., N or NR wherein R is H or other substituents, as defined). The nitrogen and sulfur heteroatoms may optionally be oxidized (i.e., N→O and S(═O)_(p), where p=1 or 2). It is to be noted that total number of S and O atoms in the aromatic heterocycle is not more than 1.

Furthermore, the terms “aryl” and “heteroaryl” include multicyclic aryl and heteroaryl groups, e.g., tricyclic or bicyclic rings.

In the case of multicyclic aromatic rings, only one of the rings needs to be aromatic (e.g., 2,3-dihydroindole), although all of the rings may be aromatic (e.g., quinoline). The second ring can also be fused or bridged.

The cycloalkyl, heterocycloalkyl, aryl, or heteroaryl ring can be substituted at one or more ring positions (e.g., the ring-forming carbon or heteroatom such as N) with such substituents as described above, for example, alkyl, alkenyl, alkynyl, halogen, hydroxyl, oxo, alkoxy, alkylcarbonyloxy, arylcarbonyloxy, alkoxycarbonyloxy, aryloxycarbonyloxy, carboxylate, alkylcarbonyl, alkylaminocarbonyl, aralkylaminocarbonyl, alkenylaminocarbonyl, alkylcarbonyl, arylcarbonyl, aralkylcarbonyl, alkenylcarbonyl, alkoxycarbonyl, aminocarbonyl, alkylthiocarbonyl, phosphate, phosphonato, phosphinato, amino (including alkylamino, dialkylamino, arylamino, diarylamino and alkylarylamino), acylamino (including alkylcarbonylamino, arylcarbonylamino, carbamoyl and ureido), amidino, imino, sulfhydryl, alkylthio, arylthio, thiocarboxylate, sulfates, alkylsulfinyl, sulfonato, sulfamoyl, sulfonamido, nitro, trifluoromethyl, cyano, azido, heterocyclyl, alkylaryl, or an aromatic or heteroaromatic moiety. Aryl and heteroaryl groups can also be fused or bridged with alicyclic or heterocyclic rings, which are not aromatic so as to form a multicyclic system (e.g., tetralin, methylenedioxyphenyl).

The term “substituted,” as used herein, means that any one or more hydrogen atoms on the designated atom is replaced with a selection from the indicated groups, provided that the designated atom's normal valency is not exceeded, and that the substitution results in a stable compound. When a moiety is indicated as substituted with one or more substituents, this typically indicates substitution with 1, 2, 3, 4, 5, or more, including 1 to 5, 1 to 4, 1 to 3, 1 to 2 or 1 substituents independently selected from an indicated group. When a substituent is oxo or keto (i.e., ═O), then 2 hydrogen atoms on the atom are replaced. Keto substituents are not present on aromatic moieties. Ring double bonds, as used herein, are double bonds that are formed between two adjacent ring atoms (e.g., C═C, C═N or N═N). “Stable compound” and “stable structure” are meant to indicate a compound that is sufficiently robust to survive isolation to a useful degree of purity from a reaction mixture, and formulation into an efficacious therapeutic agent.

When a bond to a substituent is shown to cross a bond connecting two atoms in a ring, then such substituent may be bonded to any atom in the ring. When a substituent is listed without indicating the atom via which such substituent is bonded to the rest of the compound of a given formula, then such substituent may be bonded via any atom in such formula. Combinations of substituents and/or variables are permissible, but only if such combinations result in stable compounds.

When any variable (e.g., X¹) occurs more than one time in any constituent or formula for a compound, its definition at each occurrence is independent of its definition at every other occurrence. Thus, for example, if a group is shown to be substituted with 0-2 X¹ moieties, then the group may optionally be substituted with up to two X¹ moieties and X¹ at each occurrence is selected independently from the definition of X¹. Also, combinations of substituents and/or variables are permissible, but only if such combinations result in stable compounds.

The term “hydroxy” or “hydroxyl” includes groups with an —OH or —O⁻.

As used herein, “halo” or “halogen” refers to fluoro, chloro, bromo and iodo. The term “perhalogenated” generally refers to a moiety wherein all hydrogen atoms are replaced by halogen atoms. The term “haloalkyl” or “haloalkoxyl” refers to an alkyl or alkoxyl substituted with one or more halogen atoms. For example, C₁₋₆haloalkyl indicates a 1 to 6 carbon alkyl group (linear or branched) where one or more hydrogens is replaced with a halogen.

The term “carbonyl” includes compounds and moieties which contain a carbon connected with a double bond to an oxygen atom. Examples of moieties containing a carbonyl include, but are not limited to, aldehydes, ketones, carboxylic acids, amides, esters, anhydrides, etc.

The term “carboxyl” refers to —COOH or its C₁-C₆ alkyl ester.

“Acyl” includes moieties that contain the acyl radical (R—C(═O)—) or a carbonyl group. “Substituted acyl” includes acyl groups where one or more of the hydrogen atoms are replaced by, for example, alkyl groups, alkynyl groups, halogen, hydroxyl, alkylcarbonyloxy, arylcarbonyloxy, alkoxycarbonyloxy, aryloxycarbonyloxy, carboxylate, alkylcarbonyl, arylcarbonyl, alkoxycarbonyl, aminocarbonyl, alkylaminocarbonyl, dialkylaminocarbonyl, alkylthiocarbonyl, alkoxyl, phosphate, phosphonato, phosphinato, amino (including alkylamino, dialkylamino, arylamino, diarylamino and alkylarylamino), acylamino (including alkylcarbonylamino, arylcarbonylamino, carbamoyl and ureido), amidino, imino, sulfhydryl, alkylthio, arylthio, thiocarboxylate, sulfates, alkylsulfinyl, sulfonato, sulfamoyl, sulfonamido, nitro, trifluoromethyl, cyano, azido, heterocyclyl, alkylaryl, or an aromatic or heteroaromatic moiety.

“Alkoxyalkyl,” “alkylaminoalkyl,” and “thioalkoxyalkyl” include alkyl groups, as described above, wherein oxygen, nitrogen, or sulfur atoms replace one or more hydrocarbon backbone carbon atoms.

The term “alkoxy” or “alkoxyl” includes substituted and unsubstituted alkyl groups covalently linked to an oxygen atom. Examples of alkoxy groups or alkoxyl radicals include, but are not limited to, methoxy, ethoxy, isopropyloxy, propoxy, butoxy and pentoxy groups. Examples of substituted alkoxy groups include halogenated alkoxy groups. The alkoxy groups can be substituted with groups such as alkenyl, alkynyl, halogen, hydroxyl, alkylcarbonyloxy, arylcarbonyloxy, alkoxycarbonyloxy, aryloxycarbonyloxy, carboxylate, alkylcarbonyl, arylcarbonyl, alkoxycarbonyl, aminocarbonyl, alkylaminocarbonyl, dialkylaminocarbonyl, alkylthiocarbonyl, alkoxyl, phosphate, phosphonato, phosphinato, amino (including alkylamino, dialkylamino, arylamino, diarylamino, and alkylarylamino), acylamino (including alkylcarbonylamino, arylcarbonylamino, carbamoyl and ureido), amidino, imino, sulfhydryl, alkylthio, arylthio, thiocarboxylate, sulfates, alkylsulfinyl, sulfonato, sulfamoyl, sulfonamido, nitro, trifluoromethyl, cyano, azido, heterocyclyl, alkylaryl, or an aromatic or heteroaromatic moieties. Examples of halogen substituted alkoxy groups include, but are not limited to, fluoromethoxy, difluoromethoxy, trifluoromethoxy, chloromethoxy, dichloromethoxy and trichloromethoxy.

The term “ester” includes compounds or moieties which contain a carbon or a heteroatom bound to an oxygen atom which is bonded to the carbon of a carbonyl group. The term “ester” includes alkoxycarboxy groups such as methoxycarbonyl, ethoxycarbonyl, propoxycarbonyl, butoxycarbonyl, pentoxycarbonyl, etc.

“Tautomer” is one of two or more structural isomers that exist in equilibrium and is readily converted from one isomeric form to another. This conversion results in the formal migration of a hydrogen atom accompanied by a switch of adjacent conjugated double bonds. Tautomers exist as a mixture of a tautomeric set in solution. In solutions where tautomerization is possible, a chemical equilibrium of the tautomers will be reached. The exact ratio of the tautomers depends on several factors, including temperature, solvent and pH. The concept of tautomers that are interconvertable by tautomerizations is called tautomerism.

Of the various types of tautomerism that are possible, two are commonly observed. In keto-enol tautomerism a simultaneous shift of electrons and a hydrogen atom occurs. Ring-chain tautomerism arises as a result of the aldehyde group (—CHO) in a sugar chain molecule reacting with one of the hydroxy groups (—OH) in the same molecule to give it a cyclic (ring-shaped) form as exhibited by glucose.

Common tautomeric pairs are: ketone-enol, amide-nitrile, lactam-lactim, amide-imidic acid tautomerism in heterocyclic rings (e.g., in nucleobases such as guanine, thymine and cytosine), imine-enamine and enamine-enamine. An example of keto-enol equilibria is between pyrazolo[1,5-a]pyrimidin-7(4H)-ones and the corresponding pyrazolo[1,5-a]pyrimidin-7-ol, as shown below.

It is to be understood that the compounds of the present invention may be depicted as different tautomers. It should also be understood that when compounds have tautomeric forms, all tautomeric forms are intended to be included in the scope of the present invention, and the naming of the compounds does not exclude any tautomer form. It will be understood that certain tautomers may have a higher level of activity than others.

Synthesis of pyrazolopyrimidinone and triazolopyrimidinone Compounds

The present invention provides methods for the synthesis of the compounds of any Formula disclosed herein. The present invention also provides detailed methods for the synthesis of various disclosed compounds of the present invention according to the following schemes and further exemplified for specific compounds as shown in the Examples.

Throughout the description, where compositions are described as having, including, or comprising specific components, it is contemplated that compositions also consist essentially of, or consist of, the recited components. Similarly, where methods or processes are described as having, including, or comprising specific process steps, the processes also consist essentially of, or consist of, the recited processing steps. Further, it should be understood that the order of steps or order for performing certain actions is immaterial so long as the invention remains operable. Moreover, two or more steps or actions can be conducted simultaneously.

The synthetic processes of the invention can tolerate a wide variety of functional groups, therefore various substituted starting materials can be used. The processes generally provide the desired final compound at or near the end of the overall process, although it may be desirable in certain instances to further convert the compound to a pharmaceutically acceptable salt, solvate, hydrate, ester, or prodrug thereof.

Compounds of the present invention can be prepared in a variety of ways using commercially available starting materials, compounds known in the literature, or from readily prepared intermediates, by employing standard synthetic methods and procedures either known to those skilled in the art, or which will be apparent to the skilled artisan in light of the teachings herein. Standard synthetic methods and procedures for the preparation of organic molecules and functional group transformations and manipulations can be obtained from the relevant scientific literature or from standard textbooks in the field. Although not limited to any one or several sources, classic texts such as Smith, M. B., March, J., March's Advanced Organic Chemistry: Reactions, Mechanisms, and Structure, 5^(th) edition, John Wiley & Sons: New York, 2001; Greene, T. W., Wuts, P. G. M., Protective Groups in Organic Synthesis, 3^(rd) edition, John Wiley & Sons: New York, 1999; R. Larock, Comprehensive Organic Transformations, VCH Publishers (1989); L. Fieser and M. Fieser, Fieser and Fieser's Reagents for Organic Synthesis, John Wiley and Sons (1994); and L. Paquette, ed., Encyclopedia of Reagents for Organic Synthesis, John Wiley and Sons (1995), incorporated by reference herein, are useful and recognized reference textbooks of organic synthesis known to those in the art. The following descriptions of synthetic methods are designed to illustrate, but not to limit, general procedures for the preparation of compounds of the present invention.

For example, compounds of the present invention can be prepared according to the processes illustrated below in Scheme 1, 2, 3, and 4.

Scheme 1 shows the synthesis of a compound of Formula (A), which can be a compound of Formula (I), where Y can be CR³ (Formula IA) or Y can be N (Formula IA′), R′ is R¹, and R¹, R², R³ and R⁴ are within the definitions of Formula I (see e.g. Example 5), or can provide an intermediate that can be further reacted to provide compounds of Formula I (e.g. R′ can be —C(═O)OMe, —CH₂C(═O)Me (see Examples 1 or 2), hydrogen (see Example 3 or 12). R″ is e.g. methyl or ethyl. Substituted aminopyrazoles, or aminotriazoles, many of which are commercially available or can be made by reacting a beta-keto amide with an appropriately substituted hydrazide, or by using other chemistry known to one skilled in the art, can be condensed with an appropriately substituted beta-keto ester to give compounds of A, including compounds of Formula (I).

Scheme 2 shows the synthesis of pyrazolopyrimidinones of Formulas (IId) and triazolopyrimidinones of Formula (IId′), where Y, R², R⁴, R^(a) and R^(b) are within the definitions of Formula (I). An aminopyrazole or amino triazole can be condensed with an appropriate beta-keto ester, e.g., dimethyl 2-acetylsuccinate, to give an ester (e.g. R′ of above scheme 1=CH₂C(═O)OMe, see Example 2) that is then saponified to produce an acid (compound B). The acid can then be coupled to an NR^(a)R^(b) group to give compounds of Formula (IId) or (IId′). Compounds of Formulas (IIc) or (IIc′) can be synthesized using a similar route, starting with a beta-keto ester such as dimethyl 2-acetylmalonate (e.g. scheme 1 where R′═C(═O)OMe, see Example 1).

Scheme 3 shows the synthesis of some pyrazolopyrimidinones of Formula (IIa) or triazolopyrimidinones of Formula (IIa′), where Y, R², R⁴, T¹ and X¹ are within the definitions of Formula (I). An aminopyrazole or aminotriazole can be condensed with an appropriate beta-keto ester to give compound C (e.g. scheme 1 where R′ is H) an ester that is subsequently brominated (e.g. per Example 3, the corresponding iodo compound is prepared per Example 4). The T¹-X¹ group can then be introduced through a metal-catalyzed cross-coupling reaction with an M-T¹-X¹ group to give compounds of Formula (IIa) or (IIa′). Alternatively, the brominated intermediate can be converted to a metalated nucleophile, which can then react with an electrophilic T¹-X¹ group to form compounds of Formula (IIa) or (IIa′). “M” refers to metallic functional groups such as B(OH)₂, Sn(alkyl)₃, Si(alkyl)₃, MgBr, Li, CuLi, ZnCl, and the like. Specific reactions where R′ is Br are found in Examples 3 and R′ iodo in Examples 4, 10, and 12.

Scheme 4 shows the synthesis of compounds of Formula (IIf) and (IIf) from acid Compound B (see scheme 2). Compound B can be treated with an appropriate hydrazide, e.g., acetylhydrazide, to give compounds of Formula (IIf) or (IIf) (see Examples 2 and 17). Compounds of Formula (IIe) and (IIe′) can be synthesized using a similar route, starting from the acid resulting from the reaction of 4-phenyl-3-(trifluoromethyl)-1H-pyrazol-5-amine with a beta-keto ester such as dimethyl 2-acetylmalonate (see Example 1 and 17). Additional methods of making compounds of Formula (I) are found in the Examples 1-19 below.

Compounds of the invention can also be used in the preparation of Proteolysis Targeting Chimeras (PROTACs), wherein the conjugates of the invention are conjugated to ligand that binds an E3 ubiquitin ligase via a suitable linker. For example, a compound of Formula I can be modified off of the R³ or R⁴ substituent position to provide a linker, which can be reacted to bind with a suitable ligand. Thus in one embodiment, a conjugate is provided comprising a compound of the invention that binds cGAS linked to a ligand of an E3 ubiquitin ligase, wherein the resulting conjugate binds to both the E3 ubiquitin ligase and cGAS. This results in the binding of ubiquitin to the cGAS protein by the E3 ubiquitin ligase. The resulting modified cGAS is then processed by the cell, resulting in degradation of the protein. Suitable ligands that bind E3 ubiquitin ligase, and suitable linkers, and methods of making such conjugates are well known to one skilled in the art. See, for example, Collins et al., Biochemical Journal 2017, 474:1127-1147; Bondeson, et al., Nature Chemical Biology 2015, 11:611-617; and Toure and Crews, Angew. Chem. Int. Ed. 2016, 55:2-10.

Thus, conjugates are provided comprising compounds of the invention linked to a suitable ligand. In one embodiment, compounds of Formula I can be modified by replacing or modifying the R³ or R⁴ substituent, e.g. in compounds of Formula IA, or by replacing or modifying the R⁴ substituent in compounds of Formula IA′, to provide a suitable substituent comprising a reactive group capable of binding to a suitable linker. In some embodiments, the reactive group comprises a suitable hydroxy or amine group (e.g. an R³ or R⁴ substituent or modification thereof comprising a terminal —OH, —NH₂, C(═O)NH₂, and the like) that is capable of reacting with a suitable linker. In one embodiment, compounds of Formula I can be modified by replacing or modifying the R³ or R⁴ substituent, e.g. in compounds of Formula IA, or by replacing or modifying the R⁴ substituent in compounds of Formula IA′, to provide a suitable substituent bound to a linker moiety, wherein said linker moiety comprises a reactive group capable of binding to a suitable ligand. In one embodiment, compounds of Formula I can be modified by replacing or modifying the R³ or R⁴ substituent, e.g. in compounds of Formula IA, or by replacing or modifying the R⁴ substituent in compounds of Formula IA′, to provide a suitable substituent bound to a linker moiety, wherein said linker moiety is bound to a suitable ligand. In one embodiment, the ligand binds to an E3 ubiquitin ligase. In some embodiments, the E3 ubiquitin ligase is MDM2, cIAP1, CRBN, or VHL. In one embodiment, a modified compound of the invention is a compound of Formula (Va), Formula (Vb), or Formula (Vc):

or a pharmaceutically acceptable salt, pharmaceutically acceptable solvate or pharmaceutically acceptable hydrate thereof. In these formulae, A is an E3 ubiquitin ligase ligand; Li is a suitable linker, R²⁶ is a suitable R³ or modification or replacement of R³ (as defined in Formula I), and R²⁷ is a suitable R⁴ or modification or replacement of R⁴ (as defined in Formula I); and R¹, R², R³, and R⁴ are as defined for compounds of Formula (I).

Pharmaceutical Compositions

The present invention also provides pharmaceutical compositions comprising a compound of any Formula disclosed herein in combination with at least one pharmaceutically acceptable excipient or carrier.

A “pharmaceutical composition” is a formulation containing the compounds of the present invention in a form suitable for administration to a subject. In one embodiment, the pharmaceutical composition is in bulk or in unit dosage form. The unit dosage form is any of a variety of forms, including, for example, a capsule, an IV bag, a tablet, a single pump on an aerosol inhaler or a vial. The quantity of active ingredient (e.g., a formulation of the disclosed compound or salt, hydrate, solvate or isomer thereof) in a unit dose of composition is an effective amount and is varied according to the particular treatment involved. One skilled in the art will appreciate that it is sometimes necessary to make routine variations to the dosage depending on the age and condition of the patient. The dosage will also depend on the route of administration. A variety of routes are contemplated, including oral, pulmonary, rectal, parenteral, transdermal, subcutaneous, intravenous, intramuscular, intraperitoneal, inhalational, buccal, sublingual, intrapleural, intrathecal, intranasal, and the like. Dosage forms for the topical or transdermal administration of a compound of this invention include powders, sprays, ointments, pastes, creams, lotions, gels, solutions, patches and inhalants. In one embodiment, the active compound is mixed under sterile conditions with a pharmaceutically acceptable carrier, and with any preservatives, buffers, or propellants that are required.

As used herein, the phrase “pharmaceutically acceptable” refers to those compounds, anions, cations, materials, compositions, carriers, and/or dosage forms which are, within the scope of sound medical judgment, suitable for use in contact with the tissues of human beings and animals without excessive toxicity, irritation, allergic response, or other problem or complication, commensurate with a reasonable benefit/risk ratio.

“Pharmaceutically acceptable excipient” means an excipient that is useful in preparing a pharmaceutical composition that is generally safe, non-toxic and neither biologically nor otherwise undesirable, and includes excipient that is acceptable for veterinary use as well as human pharmaceutical use. A “pharmaceutically acceptable excipient” as used in the specification and claims includes both one and more than one such excipient.

A pharmaceutical composition of the invention is formulated to be compatible with its intended route of administration. Examples of routes of administration include parenteral, e.g., intravenous, intradermal, subcutaneous, oral (e.g., inhalation), transdermal (topical), and transmucosal administration. Solutions or suspensions used for parenteral, intradermal, or subcutaneous application can include the following components: a sterile diluent such as water for injection, saline solution, fixed oils, polyethylene glycols, glycerine, propylene glycol or other synthetic solvents; antibacterial agents such as benzyl alcohol or methyl parabens; antioxidants such as ascorbic acid or sodium bisulfite; chelating agents such as ethylenediaminetetraacetic acid; buffers such as acetates, citrates or phosphates, and agents for the adjustment of tonicity such as sodium chloride or dextrose. The pH can be adjusted with acids or bases, such as hydrochloric acid or sodium hydroxide. The parenteral preparation can be enclosed in ampoules, disposable syringes or multiple dose vials made of glass or plastic.

A compound or pharmaceutical composition of the invention can be administered to a subject in many of the well-known methods currently used for chemotherapeutic treatment. The dose chosen should be sufficient to constitute effective treatment but not so high as to cause unacceptable side effects. The state of the disease condition and the health of the patient should preferably be closely monitored during and for a reasonable period after treatment.

The term “therapeutically effective amount”, as used herein, refers to an amount of a pharmaceutical agent to treat, ameliorate, or prevent an identified disease or condition, or to exhibit a detectable therapeutic or inhibitory effect. The effect can be detected by any assay method known in the art. The precise effective amount for a subject will depend upon the subject's body weight, size, and health; the nature and extent of the condition; and the therapeutic or combination of therapeutics selected for administration. Therapeutically effective amounts for a given situation can be determined by routine experimentation that is within the skill and judgment of the clinician.

For any compound, the therapeutically effective amount can be estimated initially either in cell culture assays, e.g., of neoplastic cells, or in animal models, usually rats, mice, rabbits, dogs, or pigs. The animal model may also be used to determine the appropriate concentration range and route of administration. Such information can then be used to determine useful doses and routes for administration in humans. Therapeutic/prophylactic efficacy and toxicity may be determined by standard pharmaceutical procedures in cell cultures or experimental animals, e.g., ED₅₀ (the dose therapeutically effective in 50% of the population) and LD₅₀ (the dose lethal to 50% of the population). The dose ratio between toxic and therapeutic effects is the therapeutic index, and it can be expressed as the ratio, LD₅₀/ED₅₀. Pharmaceutical compositions that exhibit large therapeutic indices are preferred. The dosage may vary within this range depending upon the dosage form employed, sensitivity of the patient, and the route of administration.

Dosage and administration are adjusted to provide sufficient levels of the active agent(s) or to maintain the desired effect. Factors which may be taken into account include the severity of the disease state, general health of the subject, age, weight, and gender of the subject, diet, time and frequency of administration, drug combination(s), reaction sensitivities, and tolerance/response to therapy. Long-acting pharmaceutical compositions may be administered every 3 to 4 days, every week, or once every two weeks depending on half-life and clearance rate of the particular formulation.

The pharmaceutical compositions containing active compounds of the present invention may be manufactured in a manner that is generally known, e.g., by means of conventional mixing, dissolving, granulating, dragee-making, levigating, emulsifying, encapsulating, entrapping, or lyophilizing processes. Pharmaceutical compositions may be formulated in a conventional manner using one or more pharmaceutically acceptable carriers comprising excipients and/or auxiliaries that facilitate processing of the active compounds into preparations that can be used pharmaceutically. Of course, the appropriate formulation is dependent upon the route of administration chosen.

Pharmaceutical compositions suitable for injectable use include sterile aqueous solutions (where water soluble) or dispersions and sterile powders for the extemporaneous preparation of sterile injectable solutions or dispersion. For intravenous administration, suitable carriers include physiological saline, bacteriostatic water, Cremophor EL™ (BASF, Parsippany, N.J.) or phosphate buffered saline (PBS). In all cases, the composition must be sterile and should be fluid to the extent that easy syringeability exists. It must be stable under the conditions of manufacture and storage and must be preserved against the contaminating action of microorganisms such as bacteria and fungi. The carrier can be a solvent or dispersion medium containing, for example, water, ethanol, polyol (for example, glycerol, propylene glycol, and liquid polyethylene glycol, and the like), and suitable mixtures thereof. The proper fluidity can be maintained, for example, by the use of a coating such as lecithin, by the maintenance of the required particle size in the case of dispersion and by the use of surfactants. Prevention of the action of microorganisms can be achieved by various antibacterial and antifungal agents, for example, parabens, chlorobutanol, phenol, ascorbic acid, thimerosal, and the like. In many cases, it will be preferable to include isotonic agents, for example, sugars, polyalcohols such as mannitol and sorbitol, and sodium chloride in the composition. Prolonged absorption of the injectable compositions can be brought about by including in the composition an agent which delays absorption, for example, aluminum monostearate and gelatin.

Sterile injectable solutions can be prepared by incorporating the active compound in the required amount in an appropriate solvent with one or a combination of ingredients enumerated above, as required, followed by filtered sterilization. Generally, dispersions are prepared by incorporating the active compound into a sterile vehicle that contains a basic dispersion medium and the required other ingredients from those enumerated above. In the case of sterile powders for the preparation of sterile injectable solutions, methods of preparation are vacuum drying and freeze-drying that yields a powder of the active ingredient plus any additional desired ingredient from a previously sterile-filtered solution thereof.

In general, a compound of the application will be administered in therapeutically effective amounts via any of the usual and acceptable modes known in the art, either singly or in combination with one or more therapeutic agents. A therapeutically effective amount may vary widely depending on the severity of the disease, the age and relative health of the subject, the potency of the compound used and other factors. Therapeutic amounts or doses will also vary depending on route of administration, as well as the possibility of co-usage with other agents.

Upon improvement of a subject's condition, a maintenance dose of a compound, composition or combination of this application may be administered, if necessary. Subsequently, the dosage or frequency of administration, or both, may be reduced, as a function of the symptoms, to a level at which the improved condition is retained when the symptoms have been alleviated to the desired level, treatment should cease. The subject may, however, require intermittent treatment on a long-term basis upon any recurrence of disease symptoms.

It will be understood, however, that the total daily usage of the compounds and compositions of the present application will be decided by the attending physician within the scope of sound medical judgment. The specific inhibitory dose for any particular patient will depend upon a variety of factors including the disorder being treated and the severity of the disorder; the activity of the specific compound employed; the specific composition employed; the age, body weight, general health, sex and diet of the patient; the time of administration, route of administration, and rate of excretion of the specific compound employed; the duration of the treatment; drugs used in combination or coincidental with the specific compound employed; and like factors well known in the medical arts.

The term “pharmaceutical combination” as used herein means a product that results from the mixing or combining of more than one active ingredient and includes both fixed and non-fixed combinations of the active ingredients. The term “fixed combination” means that the active ingredients, e.g., a compound of the application and a co-agent, are both administered to a patient simultaneously in the form of a single entity or dosage. The term “non-fixed combination” means that the active ingredients, e.g., a compound of the application and a co-agent, are both administered to a patient as separate entities either simultaneously, concurrently or sequentially with no specific time limits, wherein such administration provides therapeutically effective levels of the two compounds in the body of the patient. The latter also applies to cocktail therapy, e.g., the administration of three or more active ingredients.

Oral compositions generally include an inert diluent or an edible pharmaceutically acceptable carrier. They can be enclosed in gelatin capsules or compressed into tablets. For the purpose of oral therapeutic administration, the active compound can be incorporated with excipients and used in the form of tablets, troches, or capsules. Oral compositions can also be prepared using a fluid carrier for use as a mouthwash, wherein the compound in the fluid carrier is applied orally and swished and expectorated or swallowed. Pharmaceutically compatible binding agents, and/or adjuvant materials can be included as part of the composition. The tablets, pills, capsules, troches and the like can contain any of the following ingredients, or compounds of a similar nature: a binder such as microcrystalline cellulose, gum tragacanth or gelatin; an excipient such as starch or lactose, a disintegrating agent such as alginic acid, Primogel, or corn starch; a lubricant such as magnesium stearate or Sterotes; a glidant such as colloidal silicon dioxide; a sweetening agent such as sucrose or saccharin; or a flavoring agent such as peppermint, methyl salicylate, or orange flavoring.

For administration by inhalation, the compounds are delivered in the form of an aerosol spray from pressured container or dispenser, which contains a suitable propellant, e.g., a gas such as carbon dioxide, or a nebulizer.

Systemic administration can also be by transmucosal or transdermal means. For transmucosal or transdermal administration, penetrants appropriate to the barrier to be permeated are used in the formulation. Such penetrants are generally known in the art, and include, for example, for transmucosal administration, detergents, bile salts, and fusidic acid derivatives. Transmucosal administration can be accomplished through the use of nasal sprays or suppositories. For transdermal administration, the active compounds are formulated into ointments, salves, gels, or creams as generally known in the art.

The active compounds can be prepared with pharmaceutically acceptable carriers that will protect the compound against rapid elimination from the body, such as a controlled release formulation, including implants and microencapsulated delivery systems. Biodegradable, biocompatible polymers can be used, such as ethylene vinyl acetate, polyanhydrides, polyglycolic acid, collagen, polyorthoesters, and polylactic acid. Methods for preparation of such formulations will be apparent to those skilled in the art. Liposomal suspensions (including liposomes targeted to infected cells with monoclonal antibodies to viral antigens) can also be used as pharmaceutically acceptable carriers. These can be prepared according to methods known to those skilled in the art, for example, as described in U.S. Pat. No. 4,522,811.

It can be advantageous to formulate oral or parenteral compositions in dosage unit form for ease of administration and uniformity of dosage. Dosage unit form as used herein refers to physically discrete units suited as unitary dosages for the subject to be treated; each unit containing a predetermined quantity of active compound calculated to produce the desired therapeutic effect in association with the required pharmaceutical carrier. The specification for the dosage unit forms of the invention are dictated by and directly dependent on the unique characteristics of the active compound and the particular therapeutic effect to be achieved.

In therapeutic applications, the dosages of the pharmaceutical compositions used in accordance with the invention vary depending on the agent, the age, weight, and clinical condition of the recipient patient, and the experience and judgment of the clinician or practitioner administering the therapy, among other factors affecting the selected dosage. Generally, the dose should be sufficient to result in slowing, and preferably regressing, the progression of the autoimmune, neurodegenerative, or inflammatory disease. Dosages can be in single, divided, or continuous doses (which dose may be adjusted for the patient's weight in kg, body surface area in m², and age in years). An effective amount of a pharmaceutical agent is that which provides an objectively identifiable improvement as noted by the clinician or other qualified observer. As used herein, the term “dosage effective manner” refers to amount of an active compound to produce the desired biological effect in a subject or cell.

The pharmaceutical compositions can be included in a container, pack, or dispenser together with instructions for administration.

The compounds of the present invention are capable of further forming salts. All of these forms are also contemplated within the scope of the claimed invention.

As used herein, “pharmaceutically acceptable salts” refer to derivatives of the compounds of the present invention wherein the parent compound is modified by making acid or base salts thereof. Examples of pharmaceutically acceptable salts include, but are not limited to, mineral or organic acid salts of basic residues such as amines, alkali or organic salts of acidic residues such as carboxylic acids, and the like. The pharmaceutically acceptable salts include the conventional non-toxic salts or the quaternary ammonium salts of the parent compound formed, for example, from non-toxic inorganic or organic acids. For example, such conventional non-toxic salts include, but are not limited to, those derived from inorganic and organic acids selected from 2-acetoxybenzoic, 2-hydroxyethane sulfonic, acetic, ascorbic, benzene sulfonic, benzoic, bicarbonic, bisulfate, bitartric, boric, bromic, butyric, calcium, calcium edetic, camsylate, carbonic, chloric, citric, clavularic, dihydrochloric, edetic, ethane disulfonic, 1,2-ethane sulfonic, estolate, esylate, fumaric, glucoheptonic, gluconic, glutamic, glycolic, glycollyarsanilic, hexafluorophosphoric, hexylresorcinic, hydrabamic, hydrobromic, hydrochloric, hydroiodic, hydroxymaleic, hydroxynaphthoic, iodic, isethionic, lactic, lactobionic, lauryl sulfonic, maleic, malic, mandelic, methane sulfonic, methylbromic, methylnitric, napsylic, nitric, N-methylglucamine ammonium salt, 3-hydroxy-2-naphthoic, oleic, oxalic, pamoic, pantothenic, phenylacetic, phosphoric, polygalacturonic, propionic, salicyclic, stearic, subacetic, succinic, sulfamic, sulfanilic, sulfuric, sulfosalicylic, suramic, tannic, tartaric, toluene sulfonic, tosyl, triethiodic, trifluoroacetic, and valeric and the commonly occurring amine acids, e.g., glycine, alanine, phenylalanine, arginine, etc.

In addition to pharmaceutically acceptable salts, the compounds and pharmaceutically acceptable salts as disclosed herein can be “pharmaceutically acceptable solvates”, or where the solvent is water, “pharmaceutically acceptable hydrates”. For example, pharmaceutically acceptable solvates may be formed wherein solvent molecules are incorporated into the crystalline lattice during crystallization. Solvates may involve nonaqueous solvents such as ethanol, isopropanol, dimethyl sulfoxide, acetic acid, ethanolamine, and ethyl acetate, or they may involve water as the solvent that is incorporated into the crystalline lattice. Solvates wherein water is the solvent that is incorporated into the crystalline lattice are typically referred to as “hydrates.” Hydrates include stoichiometric hydrates as well as compositions containing variable amounts of water. The invention includes all such solvates or hydrates

When a disclosed compound or its salt is named or depicted by structure, it is to be understood that the compound or salt, including solvates or hydrates thereof, may exist in crystalline forms, non-crystalline forms or a mixture thereof. The compound or salt, or solvates or hydrates thereof, may also exhibit polymorphism (i.e. the capacity to occur in different crystalline forms). These different crystalline forms are typically known as “polymorphs.” It is to be understood that when named or depicted by structure, the disclosed compound, or solvates or hydrates thereof, also include all polymorphs thereof. Polymorphs have the same chemical composition but differ in packing, geometrical arrangement, and other descriptive properties of the crystalline solid state. Polymorphs may have different physical properties such as density, shape, hardness, stability, and dissolution properties. Polymorphs typically exhibit different melting points, IR spectra, and X-ray powder diffraction patterns, which may be used for identification. One of ordinary skill in the art will appreciate that different polymorphs may be produced, for example, by changing or adjusting the conditions used during the crystallization or recrystallization of the compounds described herein.

Other examples of pharmaceutically acceptable salts include hexanoic acid, cyclopentane propionic acid, pyruvic acid, malonic acid, 3-(4-hydroxybenzoyl)benzoic acid, cinnamic acid, 4-chlorobenzenesulfonic acid, 2-naphthalenesulfonic acid, 4-toluenesulfonic acid, camphorsulfonic acid, 4-methylbicyclo-[2.2.2]-oct-2-ene-1-carboxylic acid, 3-phenylpropionic acid, trimethylacetic acid, tertiary butylacetic acid, muconic acid, and the like. The present invention also encompasses salts formed when an acidic proton present in the parent compound either is replaced by a metal ion, e.g., an alkali metal ion, an alkaline earth ion, or an aluminum ion; or coordinates with an organic base such as ethanolamine, diethanolamine, triethanolamine, tromethamine, N-methylglucamine, and the like. In the salt form, it is understood that the ratio of the compound to the cation or anion of the salt can be 1:1, or any ration other than 1:1, e.g., 3:1, 2:1, 1:2, or 1:3.

It should be understood that all references to pharmaceutically acceptable salts include solvent addition forms (solvates) or crystal forms (polymorphs) as defined herein, of the same salt.

The compounds of the present invention can also be prepared as esters, for example, pharmaceutically acceptable esters. For example, a carboxylic acid function group in a compound can be converted to its corresponding ester, e.g., a methyl, ethyl or other ester. Also, an alcohol group in a compound can be converted to its corresponding ester, e.g., acetate, propionate or other ester.

The compounds of the present invention can also be prepared as prodrugs, for example, pharmaceutically acceptable prodrugs. The terms “pro-drug” and “prodrug” are used interchangeably herein and refer to any compound which releases an active parent drug in vivo. Since prodrugs are known to enhance numerous desirable qualities of pharmaceuticals (e.g., solubility, bioavailability, manufacturing, etc.), the compounds of the present invention can be delivered in prodrug form. Thus, the present invention is intended to cover prodrugs of the presently claimed compounds, methods of delivering the same and compositions containing the same. “Prodrugs” are intended to include any covalently bonded carriers that release an active parent drug of the present invention in vivo when such prodrug is administered to a subject. Prodrugs in the present invention are prepared by modifying functional groups present in the compound in such a way that the modifications are cleaved, either in routine manipulation or in vivo, to the parent compound. Prodrugs include compounds of the present invention wherein a hydroxy, amino, sulfhydryl, carboxy or carbonyl group is bonded to any group that may be cleaved in vivo to form a free hydroxyl, free amino, free sulfhydryl, free carboxy or free carbonyl group, respectively.

Examples of prodrugs include, but are not limited to, esters (e.g., acetate, dialkylaminoacetates, formates, phosphates, sulfates and benzoate derivatives) and carbamates (e.g., N,N-dimethylaminocarbonyl) of hydroxy functional groups, esters (e.g., ethyl esters, morpholinoethanol esters) of carboxyl functional groups, N-acyl derivatives (e.g., N-acetyl)N-Mannich bases, Schiff bases and enaminones of amino functional groups, oximes, acetals, ketals and enol esters of ketone and aldehyde functional groups in compounds of the invention, and the like, See Bundegaard, H., Design of Prodrugs, p 1-92, Elesevier, New York-Oxford (1985).

The compounds, or pharmaceutically acceptable salts, esters or prodrugs thereof, are administered by a route selected from the group consisting of enterally, orally, nasally, transdermally, pulmonary, inhalationally, buccally, sublingually, intraperintoneally, subcutaneously, intramuscularly, intravenously, rectally, intrapleurally, intrathecally and parenterally. In one embodiment, the compound is administered orally. One skilled in the art will recognize the advantages of certain routes of administration.

The dosage regimen utilizing the compounds is selected in accordance with a variety of factors including type, species, age, weight, sex and medical condition of the patient; the severity of the condition to be treated; the route of administration; the renal and hepatic function of the patient; and the particular compound or salt thereof employed. An ordinarily skilled physician or veterinarian can readily determine and prescribe the effective amount of the drug required to prevent, counter, or arrest the progress of the condition.

Techniques for formulation and administration of the disclosed compounds of the invention can be found in Remington: the Science and Practice of Pharmacy, 19^(th) edition, Mack Publishing Co., Easton, Pa. (1995). In an embodiment, the compounds described herein, and the pharmaceutically acceptable salts thereof, are used in pharmaceutical preparations in combination with a pharmaceutically acceptable carrier or diluent. Suitable pharmaceutically acceptable carriers include inert solid fillers or diluents and sterile aqueous or organic solutions. The compounds will be present in such pharmaceutical compositions in amounts sufficient to provide the desired dosage amount in the range described herein.

All percentages and ratios used herein, unless otherwise indicated, are by weight. Other features and advantages of the present invention are apparent from the different examples. The provided examples illustrate different components and methodology useful in practicing the present invention. The examples do not limit the claimed invention. Based on the present disclosure the skilled artisan can identify and employ other components and methodology useful for practicing the present invention.

In the synthetic schemes described herein, compounds may be drawn with one particular configuration for simplicity. Such particular configurations are not to be construed as limiting the invention to one or another isomer, tautomer, regioisomer or stereoisomer, nor does it exclude mixtures of isomers, tautomers, regioisomers or stereoisomers; however, it will be understood that a given isomer, tautomer, regioisomer or stereoisomer may have a higher level of activity than another isomer, tautomer, regioisomer or stereoisomer.

Compounds designed, selected and/or optimized by methods described above, once produced, can be characterized using a variety of assays known to those skilled in the art to determine whether the compounds have biological activity. For example, the molecules can be characterized by conventional assays, including but not limited to those assays described below, to determine whether they have a predicted activity, binding activity and/or binding specificity.

Furthermore, high-throughput screening can be used to speed up analysis using such assays. As a result, it can be possible to rapidly screen the molecules described herein for activity, using techniques known in the art. General methodologies for performing high-throughput screening are described, for example, in Devlin (1998) High Throughput Screening, Marcel Dekker; and U.S. Pat. No. 5,763,263. High-throughput assays can use one or more different assay techniques including, but not limited to, those described below.

Synthesis of N-(4-methoxyphenyl)-5-methyl-7-oxo-3-phenyl-2-(trifluoromethyl)-4,7-dihydropyrazolo[1,5-a]pyrimidine-6-carboxamide (A1001) was carried out in three steps as follows:

Step 1:

Synthesis of methyl 5-methyl-7-oxo-3-phenyl-2-(trifluoromethyl)-4,7-dihydropyrazolo[1,5-a]pyrimidine-6-carboxylate (I-3). To a stirred solution of 4-phenyl-3-(trifluoromethyl)-1H-pyrazol-5-amine (I-1, 2.00 g, 8.80 mmol) (WO 2012149157) in AcOH (10 mL) was added dimethyl 2-acetylmalonate (I-2, 1.3 eq, 1.99 g, 11.4 mmol) (JACS, 136(34), 12137-12160, 2014). The reaction mixture was heated at 100° C. for 30 min and concentrated in vacuo to dryness. The reaction mixture was triturated in EtOAc for 15 min. The solid was collected by filtration, rinsed with EtOAc, dried under high vacuum to afford the compound I-3 (1.60 g, 4.55 mmol, 52%) as a white solid which was used without further purification. ¹H NMR (500 MHz, DMSO) δ 12.69 (s, 1H), 7.54-7.45 (m, 3H), 7.45-7.42 (m, 2H), 3.81 (s, 3H), 2.43 (s, 3H); MS (m/z): 325.0 [M+1]⁺, 97.2%.

Step 2:

Example 2

Synthesis of N-(2-aminophenyl)-2-(5-methyl-7-oxo-3-phenyl-2-(trifluoromethyl)-4,7-dihydropyrazolo[1,5-a]pyrimidin-6-yl)acetamide (B1001) was carried out in three steps as follows:

Step 1:

Synthesis of methyl 2-(5-methyl-7-oxo-3-phenyl-2-(trifluoromethyl)-4,7-dihydropyrazolo[1,5-a]pyrimidin-6-yl)acetate (I-7): To a stirred solution of 4-phenyl-3-(trifluoromethyl)-1H-pyrazol-5-amine (I-1, 2.00 g, 8.80 mmol) (WO 2012149157) in AcOH (15 mL) was added dimethyl 2-acetylsuccinate (I-6, 1.5 eq, 2.48 g, 13.2 mmol). The reaction mixture was heated at 100° C. for 5 h and concentrated to dryness. The reaction mixture was triturated in EtOAc for 15 min. The solid was collected by filtration, rinsed with EtOAc, and dried in vacuo to afford compound I-7 (2.38 g, 6.51 mmol, 74%) as a white solid which was used without further purification. ¹H NMR (500 MHz, DMSO) δ 12.27 (s, 1H), 7.56-7.39 (m, 5H), 3.63 (s, 3H), 3.61 (s, 2H), 2.34 (s, 3H); MS (m/z): 365.9 [M+1]⁺, 99.3%.

In a separate flask, oxalyl chloride (383 μL, 4.43 mmol) is dissolved in DCM (3.41 mL) and cooled to 0-4° C. using an ice/water bath. To this solution is added DMF (343 μL, 4.43 mmol) and the resulting mixture is added dropwise to the suspension of compound I-11. The reaction mixture is stirred at 0-4° C. and gradually warmed to room temperature. After overnight at room temperature, the reaction mixture is poured into a mixture of ice and 1M NaOH aqueous solution. EtOAc is then added and layers are separated. The organic layer is washed with brine, dried over anhydrous Na₂SO₄, filtered and concentrated in vacuo. The crude oil was purified by normal phase chromatography (SiO₂, using a gradient of 0 to 20% MeOH in DCM) to afford the compound I-17. MS (m/z): 322.0 [M+1]⁺, 92.25%.

Step 2:

The reaction mixture was placed in a preheated oil bath at 90° C. overnight. After this time, reaction mixture was cooled to room temperature and TEMPO (2.5 mg, 0.016 mmol), followed by iron(III) acetylacetonate (11 mg, 0.031 mmol) were added. O₂ was bubbled into the dark solution for 5 min and the resulting mixture was heated at 40° C. for 2 h. After this time, the reaction mixture was concentrated in vacuo to dryness. The residue was purified by reverse flash chromatography (KP-C18-H5, using a gradient 0 to 100 MeCN/H₂O (0.1% ammonium formate buffer) to afford compound C1229 after lyophilization. ¹H NMR (500 MHz, DMSO) δ 12.68 (s, 1H), 7.74 (d, J=6.9 Hz, 1H), 7.55-7.33 (m, 10H), 7.32-7.11 (m, 3H), 2.21 (s, 3H); MS (m/z): 486.1 [M+1]⁺, 99.4%.

Step 1:

Synthesis of 5-hydroxy-6-(4-methoxybenzo[d]oxazol-2-yl)-3-phenyl-2-(trifluoromethyl)pyrazolo[1,5-a]pyrimidin-7(4H)-one (I-20): A mixture of 4-phenyl-3-(trifluoromethyl)-1H-pyrazol-5-amine (I-1, 1.68 g, 7.40 mmol) and 2-(4-methoxybenzo[d]oxazol-2-yl)malonate (I-19, 2.50 g, 8.14 mmol) were dissolved in DCM (5 mL). The reaction mixture was concentrated in vacuo and the residue was heated at 120° C. for 2 h. LCMS showed complete reaction and the crude mixture was dissolved in MeOH (5 mL), and sodium methoxide in MeOH (30 mmol) was added and the reaction was stirred at r.t. for 3 h. The reaction was quenched with AcOH, and concentrated in vacuo. The desired compound was crashed out after adding water. The resulting white solid was filtered and dried in vacuo to afford compound I-20. MS (m/z): 443.0 [M+1]⁺.

Example 22: Inhibition of Cytokine Secretion by Trex1-Knockout (KO) Bone Marrow-Derived Macrophages (BMMs)

The inhibition of secreted cytokine was measured in bone marrow-derived macrophages (BMMs) from diseased mice to evaluate the potency of compounds of the invention as described herein. Mice lacking the gene for Trex1 protein (trex1−/− or Trex1-KO) exhibit cGAS/STING pathway-dependent autoimmune and autoinflammatory disease manifestations, including enhanced cytokine secretion by cells. To derive bone marrow macrophages, marrow extracted from the femurs and tibias were harvested from Trex1-KO mice was cultured in growth media supplemented with macrophage colony-stimulating factor (M-CSF). Differentiated BMM were harvested and frozen for subsequent experimentation. For treatment with compound C1089 (see Example 13), a frozen stock of Trex1-KO BMM was thawed and 1×10⁵ cells were plated in 96 well format. BMMs were treated with a dilution series of C1089 and incubated overnight at 37° C. 5% CO₂, at which point cellular supernatants were harvested and stored at −80° C. for subsequent analysis. The media used for this dilution series was without FBS. Remaining cells were evaluated for viability using Cell Titer Glo 2.0 kit according to the manufacturer instructions. BMM supernatants were evaluated for the secreted cytokine normal T cell expressed and secreted (RANTES/CCL5) or for secreted cytokine monocyte chemoattractant protein 1 (MCP-1/CCL2) using cytometric bead array mouse Flex Set kits (BD Biosciences). Cytokine concentration was calculated from a standard curve and normalized to vehicle (DMSO) treated cells.

FIG. 1 shows that C1089 can significantly inhibit cytokine secretion by diseased Trex1-KO BMM (RANTES/CCL5 IC₅₀=1.251 μM, MCP-1/CCL2 IC₅₀=6.973 μM). Additionally, BMM were 100% viable at these concentrations, indicating that inhibition is not simply due to cellular cytotoxicity. Additional compounds were assessed by this assay.

Table 17 below provides IC₅₀ data for certain compounds of the invention for inhibition of RANTES expression. “A” indicates an IC₅₀ value less than 5 μM, “B” indicates an IC₅₀ value between 5 and 20 μM, and “C” indicates where an IC₅₀ value could not be calculated from the data. ND indicates no data for that cytokine. In this table, column M refers to MCP-1 and column R refers to RANTES.
